This present application claims the benefit of the earlier filing date of provisional patent application No. 62/799,131, filed Jan. 31, 2019, the entire contents of which being incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to a method and a server to be used for autonomous driving; and more particularly, to the method for providing an autonomous driving service platform to be used for supporting an autonomous driving of vehicles by using competitive computing and an information fusion, and the server using the same.

BACKGROUND OF THE DISCLOSURE

Autonomous vehicles use various computing systems to aid in transport of passengers from one location to another. Some autonomous vehicles may require some initial input or continuous input from an operator, such as a pilot, driver, or passenger. Other systems, for example, autopilot systems, may be used only when the system has been engaged, which permits the operator to switch from a manual driving mode (where the operator exercises a high degree of control over a movement of the vehicle) to an autonomous driving mode (where the vehicle essentially drives itself).

Such vehicles are typically equipped with various types of sensors in order to detect objects in the environment. For example, autonomous vehicles may include LIDARs, sonar, radar, cameras, and other devices which scan and record data from the vehicle's environment. Sensor data from one or more of these devices may be used to detect objects and their respective characteristics (position, shape, heading, speed, etc.).

However, conventional autonomous driving vehicles perform autonomous driving according to their own autonomous driving algorithms based on a deep learning, and accordingly different results are derived from different autonomous driving algorithms even in the same driving environment, and as a result stability of the autonomous driving cannot be guaranteed.

Therefore, the inventors of the present disclosure propose a method for improving an accuracy and a stability of an autonomous driving algorithm.

SUMMARY OF THE DISCLOSURE

It is an object of the present disclosure to solve all the aforementioned problems.

It is another object of the present disclosure to improve an accuracy and a stability of at least one autonomous driving algorithm.

FIG. 1 is a drawing schematically illustrating a configuration of a service server for providing an autonomous driving service platform to be used for supporting an autonomous driving of autonomous vehicles by using a competitive computing and an information fusion in accordance with one example embodiment of the present disclosure.

By referring to FIG. 1, the service server 100 may include a sensor data collection unit 130, a data transmission unit 140, a vehicle management unit 150, a data processing server management unit 160, a result transmission unit 170, a result receiving unit 180 and a server ranking unit 190 to be described later.

However, detailed communication schematics between the communication part 110 and the processor 120 are omitted in FIG. 1. Herein, a memory 115 may have stored various instructions to be described later, and the processor 120 may execute the instructions stored in the memory 115 and may perform processes of the present disclosure by executing the instructions to be disclosed later. Such description of the service server 100 does not exclude an integrated device including any combination of a processor, a memory, a medium, or any other computing components.

Herein, said units, i.e., the sensor data collection unit 130, the data transmission unit 140, the vehicle management unit 150, the data processing server management unit 160, the result transmission unit 170, the result receiving unit 180 and the server ranking unit 190, may be based on individual hardware units interworking with the service server 100 and/or software installed on the service server 100, but a scope of the present disclosure may not be limited thereto.

Such service server 100 may interwork with a subject vehicle 200. A configuration of the subject vehicle 200 may be explained below by referring to FIG. 2.

FIG. 2 is a drawing schematically illustrating the configuration of the subject vehicle interworking with the service server for providing the autonomous driving service platform to be used for supporting the autonomous driving of the autonomous vehicles by using the competitive computing and the information fusion in accordance with one example embodiment of the present disclosure.

By referring to FIG. 2, the subject vehicle 200 may include a sensor input unit 210, a sensor data transmission unit 220, a platform connection unit 230, a verification unit 240, a result receiving unit 250, a feedback transmission unit 260 and a result integration unit 270. The subject vehicle 200 may be one of the autonomous vehicles which performs an autonomous driving by using the service server 100. Specifically, the autonomous vehicles may perform the autonomous driving by using autonomous driving source information acquired from multiple data processing servers which include autonomous driving algorithms to be explained later, while using the service server 100 as a middle manager. However, the service server 100 may not only perform a simple managing processes, but also perform processes for the competitive computing and the information fusion. Such processes will be explained by referring to FIG. 3.

Herein, said units, i.e., the sensor input unit 210, the sensor data transmission unit 220, the platform connection unit 230, the verification unit 240, the result receiving unit 250, the feedback transmission unit 260 and the result integration unit 270, may be based on individual hardware units interworking with the subject vehicle 200 and/or software installed on the subject vehicle 200, but a scope of the present disclosure may not be limited thereto.

FIG. 3 is a drawing schematically illustrating correlations among the subject vehicle, the data processing servers and the service server for providing the autonomous driving service platform to be used for supporting the autonomous driving of the autonomous vehicles by using the competitive computing and the information fusion in accordance with one example embodiment of the present disclosure.

By referring to FIG. 3, correlations among units included in the subject vehicle 200 which acquires the autonomous driving source information from the data processing servers 300 through the service server 100 may be seen. Below, each of functions of each of configurations may be explained along with the method for providing the autonomous driving service platform, by referring to FIG. 3.

First, the service server 100 may continuously acquire individual sensor data and individual driving data from the autonomous vehicles. Herein, the individual sensor data, including information on surroundings of the autonomous vehicles, may be acquired through sensors installed on each of the autonomous vehicles. By referring to FIG. 3, it can be seen that the subject vehicle 200, one of said autonomous vehicles, delivers subject sensor data acquired through the sensor input unit 210 to the sensor data collection unit 130 through the sensor data transmission unit 220. As the autonomous vehicles perform processes similar to those shown above, the service server 100 may acquire the individual sensor data of the autonomous vehicles.

The individual driving data may include information on each of locations and each of velocities of the autonomous vehicles. Additionally, the individual driving data may include at least part of topographic information around the autonomous vehicles, climate information therearound, driving timing information of the autonomous vehicles, and vehicle type information thereof. In such circumstance, the service server 100 may support the subject vehicle 200 to perform the autonomous driving by using the autonomous driving source information. As a first step, the service server 100 may select specific autonomous vehicles, among the autonomous vehicles, which are related to the subject vehicle 200.

Specifically, the service server 100 may select the specific autonomous vehicles, among the autonomous vehicles, which satisfy at least one of a direct interaction condition corresponding to a relationship between a subject location of the subject vehicle and one or more individual locations of the autonomous vehicles and an indirect interaction condition corresponding to individual motion information of the autonomous vehicles. According to the direct interaction condition, the specific autonomous vehicles may be selected by finding ones whose differences between the individual locations and the subject location are smaller than a first threshold. Also, according to the indirect interaction condition, the specific autonomous vehicles may be selected by finding ones whose differences between the individual locations and the subject location are expected, by referring to the individual motion information including information on the velocities thereof, to become smaller than the first threshold after a certain time, although the differences are larger than or same as the first threshold.

Thereafter, the service server 100 may deliver specific sensor data of the specific autonomous vehicles to the data processing servers 300 through the data transmission unit 140. Herein, the data processing servers 300 may include autonomous driving algorithms built by using at least part of a rule-based algorithm and a deep learning algorithm, to become capable of generating the autonomous driving source information by using the autonomous driving algorithms. Also, each of the data processing servers 300 may be operated by each of different entities, e.g., different IT companies. In this case, their autonomous driving algorithms are different from each other, and may compete with each other. Such competition may be explained soon after.

As one example, each of one or more specific data processing servers, among the data processing servers 300, using each of one or more specific autonomous driving algorithms built by using the deep learning algorithm may apply a convolutional operation using its own convolutional layer to the subject sensor data and the specific sensor data to generate at least one feature map, and may apply an output operation using its own output layer to the feature map, to thereby generate each of the pieces of the autonomous driving source information.

Herein, the autonomous driving source information may include information on locations of objects located around the subject vehicle 200 and the specific autonomous vehicles, but a scope of the present disclosure may not be limited thereto. In this case, the output layer may include a pooling layer and a Fully-Connected (FC) layer to detect said locations thereof. After each of the pieces of the autonomous driving source information is acquired from each of the data processing servers 300 through the result receiving unit 180, the service server 100 may transmit the autonomous driving source information to the subject vehicle 200 through the result transmission unit 170. Herein, additional information, i.e., circumstance-specific performance information to be explained below, acquired through the server ranking unit 190, may be transmitted to the subject vehicle along with the autonomous driving source information.

That is, the service server 100 may acquire circumstance-specific performance information on the data processing servers 300 from a circumstance-specific performance DB in the server ranking unit 190 by referring to subject driving data of the subject vehicle 200. Specifically, the service server 100 may acquire at least part of topographic information around the subject vehicle 200, climate information therearound, driving timing information of the subject vehicle 200, and the vehicle type information thereof by referring to the subject driving data of the subject vehicle 200, and may transmit a query to the circumstance-specific performance DB by referring to said at least part of the topographic information, the climate information, the driving timing information and the vehicle type information, to thereby acquire the circumstance-specific performance information of the data processing servers 300. Herein, the circumstance-specific performance DB may include information on rankings of the data processing servers 300 in each of circumstances, and the circumstance-specific performance information may include information on rankings of the data processing servers 300 in a specific circumstance corresponding to the subject driving data.

After the circumstance-specific performance information is acquired as shown above, the service server 100 may deliver the autonomous driving source information and the circumstance-specific performance information to the subject vehicle 200 through the result transmission unit 170. The subject vehicle 200 may acquire the autonomous driving source information and the circumstance-specific performance information through the result receiving unit 250, and may deliver those to the verification unit 240.

Thereafter, the subject vehicle 200 may instruct the verification unit 240 to calculate each of self-verification scores on each of the pieces of the autonomous driving source information by referring to the subject sensor data. Specifically, the service server 100 may instruct at least one Convolutional Neural Network (CNN) included in the subject vehicle 200 to apply at least one CNN operation to a vector including (i) the subject sensor data and (ii) the autonomous driving source information to perform a classification, to thereby generate the self-verification scores. Herein, the CNN may include a convolutional layer and an output layer.

Then, the subject vehicle 200 may instruct the result integration unit 270 to generate integrated autonomous driving source information corresponding to each of the pieces of the autonomous driving source information by referring to at least part of the self-verification scores and the circumstance-specific performance information. Specifically, in case two different pieces of the autonomous driving source information denote different detection results on a same object, e.g., in case of a class of the same object detected as differently in the two pieces of the autonomous driving source information, one piece of the autonomous driving source information whose corresponding self-verification score is larger or whose circumstance-specific rank is higher than the others, may be determined as correct, and may be reflected on the integrated autonomous driving source information.

Thereafter, the subject vehicle 200 may become capable of performing the autonomous driving by referring to the integrated autonomous driving source information. Also, in parallel, the subject vehicle 200 may deliver the self-verification scores to the service server 100 as performance feedback information through the feedback transmission unit 260. Then, the service server 100 may update the circumstance-specific performance DB by referring to the performance feedback information. By such updating process, the circumstance-specific performance DB may be built to include information on rankings of the data processing servers 300 in each of circumstances.

Different from above-explained embodiment, there is an additional embodiment for generating the integrated autonomous driving source information and the self-verification scores. Hereinafter, the additional embodiment will be explained.

That is, the subject vehicle 200 may perform the autonomous driving by referring to the integrated autonomous driving source information generated by using each of the pieces of the autonomous driving source information and the circumstance-specific performance information at a T-th timing, and may calculate each of the self-verification scores on each of the pieces of the autonomous driving source information by using resultant circumstance information at a (T+1)-th timing, which is later than the T-th timing, corresponding to a circumstance caused by the autonomous driving performed at the T-th timing. To be simple, the subject vehicle 200 may just perform the autonomous driving by using the integrated autonomous driving source information based on the circumstance-specific performance information, may detect whether a negative circumstance, e.g., a sudden stop, a car horning or an accident, occurred or not, and may calculate at least part of the self-verification scores corresponding to at least part of the integrated autonomous driving source information which has been a basis of the autonomous driving of the T-th timing, to be smaller. By delivering such self-verification scores to the service server 100, the circumstance-specific performance DB may be updated.

Said service server 100 and the subject vehicle 200 may include some configurations for maintaining their connections. For example, the service server 100 may be connected with the autonomous vehicles including the subject vehicle 200 through the vehicle management unit 150, and may be connected with the data processing servers 300 through the data processing server management unit 160. The subject vehicle 200 may be connected with the service server 100 through the platform connection unit 230.

By providing the autonomous driving service platform, i.e., the service server 100, a safer autonomous driving using the competitive computing and the information fusion may be acquired.

It is an effect of the present disclosure to improve an accuracy and a stability of at least one autonomous driving algorithm.

It is another effect of the present disclosure to allow at least one autonomous vehicle to perform autonomous driving according to autonomous driving source information with a sufficient credibility.

It is still another effect of the present disclosure to allow safe autonomous driving by using nearby sensor data of one or more nearby autonomous vehicles.

The embodiments of the present disclosure as explained above can be implemented in a form of executable program command through a variety of computer means recordable to computer readable media. The computer readable media may include solely or in combination, program commands, data files, and data structures. The program commands recorded to the media may be components specially designed for the present disclosure or may be usable to a skilled human in a field of computer software.
